DETAILED DESCRIPTION OF THE EMBODIMENTS

A plurality of preferred embodiments of the present disclosure are introduced below with reference to the drawings of the description, making its technical contents clearer and convenient to understand. The present disclosure can be reflected by various embodiments of different forms, and the protection scope of the present disclosure is not only limited to the embodiments mentioned herein.

In the drawings, elements of the same structure are denoted by same numerals, and components similar in structures or functions are denoted by similar numerals. The size and thickness of each component shown in the drawings are shown randomly, and the present disclosure does not limit the size and thickness of each component. In order to make the illustration clearer, the thicknesses of some parts in the drawings are appropriately exaggerated.

As shown in FIG. 1 to FIG. 3, the present disclosure provides a cradle, including a base 1, a movable bed compartment 2 and a support 3. The movable bed compartment 2 is movably connected with the support 3 disposed on the base 1 in a suspended manner. In the embodiment, swing rods 4 are used to connect the movable bed compartment 2 with the support 3, making the movable bed compartment 2 moved back and forth in the force direction under a push force or a pull force. Generally, there may be four swing rods of two groups, which are respectively arranged at two ends of the movable bed compartment 2 to play a role in stabilizing the movable bed compartment 2.

A first fixed end 203 and a second fixed end 206 are disposed on the bottom face of the movable bed compartment 2 in the moving direction of the movable bed compartment 2. A wire-winding barrel 201 is located between the first fixed end 203 and the second fixed end 206, and is rotationally fixed to the face of the base 1 facing to the movable bed compartment 2, and the rotation axis of the wire-winding barrel 201 is perpendicular to the base 1. A first wire body 202 and a second wire body 205 are wound on the wire-winding barrel 201, and the winding direction of the first wire body 202 is opposite to that the winding direction of the second wire body 205. A free end of the first wire body 202 is connected with the first fixed end 203, and a free end of the second wire body 205 is connected with the second fixed end 206.

Thus, when the wire-winding barrel 201 rotates, the first wire body 202 and the second wire body 203 can drive the movable bed compartment 2 to horizontally move back and forth according to the rotation degree of the wire-winding barrel 201. In addition, the swing amplitude of horizontal to-and-fro motion can be adjusted according to the lengths of the wire bodies that are wound on the wire-winding barrel 201, namely the number of wire-winding circles.

As shown in FIG. 4, the wire-winding barrel 201 includes a first V-shaped opening 2011 and a second V-shaped opening 2012. The opening directions of the first V-shaped opening 2011 and the second V-shaped opening 2012 are consistent with the rotation direction of the wire-winding barrel 201. The first V-shaped opening 2011 and the second V-shaped opening 2012 are both provided with round holes 2013. One ends of the first wire body 202 and the second wire body 205 are fixed in the round holes 2013, so that the first wire body 202 and the second wire body 205 are tightly wound on the first V-shaped opening 2011 and the second V-shaped opening 2012, respectively.

Further, since there is a height difference when the movable bed compartment 2 is horizontally moving back and forth, the V-shaped included angle between the first V-shaped opening 2011 and the second V-shaped opening 2012 is set to be 30° to 120° to compensate the height difference and prevent the wire bodies from disengaging in the rotation process of the wire-winding barrel 201.

Further, the wire-winding barrel 201 is driven by a motor 5. The motor 5 is configured to rotate forward and backward to drive the wire-winding barrel 201, which makes the cradle swing automatically. The motor 5 may also be driven by a remote control device to achieve remote control.

Further, the cradle further includes elastic members 204. The free end of the first wire body 202 is connected with the first fixed end 203 by means of the corresponding elastic member 204, and the free end of the second wire body 205 is connected with the second fixed end 206 by means of the corresponding elastic member 204. In the embodiment, the elastic members 204 are springs. Thus, even if the motor 5 clamps an object in the swing process of the movable bed compartment 2, the motor 5 is not jammed and can still pull the elastic members 204 to rotate. The motor 5 can rotate backward to make the clamped object disengaged after rotating to a preset rotation limit, so as to avoid a situation that the motor 5 is jammed after the motor 5 does not reach its preset rotation limit for a long period of time. By adjusting the winding number of the first wire body 202 and the second wire body 205 that are wound on the wire-winding barrel 201, the tightness of the elastic members 204 can also be adjusted, which can not only reduce damage when hitting or clamping an object, but also play a role in buffering.

FIG. 5 and FIG. 6 show the schematic structural diagram of another embodiment of the present disclosure. Based on the foregoing embodiment, both sides of the movable bed compartment 2 are modified into bed compartment flaps 207, and the bed compartment flaps 207 can be flipped down by means of hinges 208 to allow a user to move a baby conveniently. In the embodiment, the hinges 208 are disposed inside the bed compartment flaps 207 and the bed compartment 2, so that the hinges can be hidden in a corresponding internal space between the bed compartment flaps 207 and the bed compartment 2 when the bed compartment flaps 207 are returned to the movable bed compartment 2.

Further, the plug pins 209 are provided on the bed compartment flaps 207. The plug pins 209 include pin tops 2091, first rod parts 2092 and second rod parts 2093. The plug pins 209 penetrate through parts of the bed compartment flaps 207 in the direction parallel to the bed compartment flaps 207, making the second rod parts 2093 exposed. The pin grooves 211 are provided in the positions, corresponding to the second rod parts 2093, on the movable bed compartment 2, and the second rod parts 2093 are inserted into the pin grooves 211 to make the bed compartment flaps 207 fixed to the movable bed compartment 2. The diameters of the first rod parts 2092 are smaller than those of the pin tops 2091 and second rod parts 2093. The springs 210 are sleeved on the first rod parts 2092, and the springs 210 can only move in through holes formed by the plug pins 209 penetrating through the bed compartment flaps 207. When the pin tops 2091 are pulled, the springs 210 are compressed, and the second rod parts 2093 leave from the pin grooves 211, making the bed compartment flaps 207 flipped down by means of the hinges 208; and when the pin tops 2091 are released, the plug pins 209 are returned by means of the springs 210.

As shown in FIG. 8, the support connection members 601 are also provided on the bottom of the cradle described in the present disclosure, and are specifically disposed on the connection corners on the bottom of the base 1 of the cradle to reinforce the base 1. The support connection members 601 can be in any shape, which is not limited herein. In the embodiment, the base 1 is a hexahedron, four support connection members 601 are respectively connected to the connection corners between four side faces on the bottom of the base 1, the rolling wheels 6 are arranged corresponding to the support connection members 601 in number, and the rolling wheels 6 are connected to the support connection members 601, so that support points of the cradle can be moved to the support connection members 601. Compared with the technical solution of the prior art in which the rolling wheels are disposed on the sides of the support, the load-bearing performance of the cradle in the present disclosure is improved, and the structure is safer.

Preferred specific embodiments of the present disclosure are described above in detail. It should be understood that those of ordinary skill in the art may make many modifications and changes according to the conception of the present disclosure without creative labor. Thus, all technical solutions that may be obtained by those skilled in the art according to the conception of the present disclosure and on the basis of the prior art through logical analysis, reasoning or limited experiments should be within the protection scope determined by the claims.
